Is Jack's Premium Duck a good dog food?
We score it 71/100 (Good). This reflects the ingredient quality, composition and label transparency of the recipe as declared on the label.
Why this score?
This recipe scores 71 out of 100. The undeclared ingredient shares, meaning ingredients without printed percentages, cost the product -10.6 points, while the overall quality of the ingredient list lifted it by +7.8. The processing format contributed +6.3, and being labelled nutritionally complete added a further +2.3.
Only part of the analytical constituents are declared, so the nutritional picture is incomplete.
100% of this recipe has no printed percentage. Estimated shares are model estimates, not label facts.

The Recipe score measures how attractive and transparent the declared ingredient list is. It is not, by itself, proof that the food is nutritionally appropriate for long-term feeding. The Nutritional and Evidence scores measure what we can verify towards that stronger claim.
Why you might choose it
- Scores 71, in the top quarter of dry foods we track.
- Single named animal protein: duck.
- Doesn't list grain ingredients.
Why you might not
- Meat makes up an estimated 5% of the dry matter (12% as fed); carbohydrates dominate.
- Only protein, fat and fibre declared; ash and moisture missing from the analysis.
- 100% of the recipe mass has no printed percentage, so the exact split cannot be verified.

Nutritional: declared analysis vs reference ranges
How the declared analysis compares with FEDIAF reference ranges for adult dogs. The label prints as-fed values; we convert to a dry-matter basis before scoring, and the bands are dry-matter ranges. Scores rise to 100 at the band midpoint: the reference is adequacy, not maximisation. Nutrients with a published upper limit taper again above it; fat is policed through calorie density rather than a direct penalty.
Guaranteed-analysis FEDIAF score: crude minimums and maximums are bounds, not typical values; moisture (a maximum) uses the processing median where available; experimental US score.
| Nutrient | As fed (label) | Dry matter (scored) | Score |
|---|---|---|---|
| Protein | 30 | 33.4 (band 18 to 40%) | 100 |
| Fat | 25 | 27.8 (band 5.5 to 20%) | 100 |
| Fibre | 2 | 2.2 (band 0.5 to 5%) | 93 |
Scored over 3 declared nutrients (combined weight 50); undeclared nutrients do not affect the score. Moisture was not declared and was estimated at 10.2% from the food type.
Low confidence: partial analysis or moisture estimated from the food type.
This measures agreement with published reference ranges, not suitability for an individual dog. For medical conditions, follow veterinary guidance.
Transparency: what the label discloses
How much the manufacturer discloses, measured against the FEDIAF Code of Good Labelling Practice and Regulation 767/2009. Mandatory items dominate the weighting.
| Item | Points |
|---|---|
| Ingredient list on the label (mandatory) | 10/10 |
| Printed percentages on the label (voluntary) - not on file | 0/20 |
| Analytical constituents declared (mandatory) - not on file | 0/15 |
| Additives declared (mandatory) | 10/10 |
| Energy value declared (voluntary) - not on file | 0/5 |
| Complete/complementary designation (mandatory) | 5/5 |
| Feeding guidance given (mandatory) - not on file | 0/10 |
| Manufacturer identity and address (mandatory) | 5/10 |
| Country of manufacture stated (voluntary) | 10/10 |
| Batch and date labelling (mandatory) - not on file | 0/5 |

Safety: recall history
Recall and safety-notice history, time-decayed. This dimension is shown alongside the score and never feeds the headline number.
No recalls recorded in our database.
Evidence: what the brand claims, and what supports it
The claims made on the pack and product page, checked against the declared label. We record claims as stated; "consistent" means our stored label data supports the claim, "contradicted" means it conflicts with it. Functional claims are recorded but never scored.
100/100 · moderate — 2 checkable claims: 2 consistent, 0 contradicted.
Consistent with the label
- "complete and balanced meal" — supported by the declared complete and balanced data.
- "high protein" — supported by the declared high protein data.
16 further claims on file that we cannot check against the label.
Moderate: every checkable claim is consistent with the declared label.
